Houston News category interest
The city will temporarily convert the disinfectant used in the water treatment process from chloramine to free chlorine. The duration of the free chlorine conversion will be approximately 30 days and will begin on March 1, 2022. The city will return to chloramine disinfection on March 29, 2022.
This change only applies to the main city water system that receives treated surface water. It will not affect customers in Riverpark, Greatwood, or New Territory, as those water systems are independent and already on free chlorine at all times.

What to expect during the temporary change
Generally, there are no noticeable changes in water quality as a result of this temporary conversion. However, some individuals may notice taste and odor changes and a slight discoloration to the water, primarily during the transition period. Noticeable water quality changes associated with conversions are normally short-lived and are not public health risks.
